1 giorno fa · Faced with these infinities, John Archibald Wheeler and Heisenberg proposed, in 1937 and 1943 respectively, to supplant the problematic QFT with the so-called S-matrix theory.
3 giorni fa · The notion of spontaneous fission had been raised by Niels Bohr and John Archibald Wheeler in their 1939 treatment of the mechanism of nuclear fission. The first attempt to discover spontaneous fission in uranium was made by Willard Libby, but he failed to detect it.
3 giorni fa · The curvature is, in turn, caused by the energy–momentum of matter. Paraphrasing the relativist John Archibald Wheeler, spacetime tells matter how to move; matter tells spacetime how to curve.
3 giorni fa · John Archibald Wheeler and partner Enrico Fermi suspected that a fission product, Xe-135, with a half-life of 9.4 hours, was the culprit, and might be a neutron poison or absorber. Segrè then remembered the 1940 PhD thesis that Wu had done for him at Berkeley on the radioactive isotopes of Xe and told Fermi to "ask Ms. Wu". [55]
28 mag 2024 · With C.W. Misner and John Archibald Wheeler, Thorne wrote Gravitation (1973), which became the standard graduate school text on general relativity. He also wrote a popular book about the subject, Black Holes and Time Warps: Einstein’s Outrageous Legacy (1994).
3 giorni fa · Feynman received a PhD from Princeton in 1942; his thesis advisor was John Archibald Wheeler.
3 giorni fa · A remark by John Archibald Wheeler that has become proverbial among physicists summarizes the theory: "Spacetime tells matter how to move; matter tells spacetime how to curve", and therefore there is no point in considering one without the other.
